Quick assessment

Affected
vworld4u office-converter
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

office-converter 1.0.2 及更早版本中存在操作系统命令注入漏洞，攻击者可通过构造恶意的 fileName 参数传入 generatePdf() 或 generateHtml() 方法，从而执行任意系统命令。攻击者可在文件名中嵌入 $(...)、反引号（` ``）或闭合引号并结合 shell 元字符，由于文件名被直接拼接至通过 child_process.exec() 执行的 unoconv 命令中，攻击者便能在 Node.js 进程权限下执行任意命令。
